--- Comment #1 from Bontas Marcel telliangun@gmail.com 2009-07-29 19:33:38 --- Note that this crash occurs no matter of what graphics options are selected in-game.
Changing resolution, enabling/disabling VSync or changing options between Low (Minimal) and Very High (Enthusiast) don't fix the crash.
Also, when a map *did* load everything was on Very High. Since then I've tried opening that map 30 times with the same options I had then but it always crashes. Hope that helps.
